3. Objective The objective of this session is to explain:
what a job hazard assessment (JHA) is
when a JHA should be used
the benefits of a JHA
JHA roles and responsibilities
the JHA process
how to fill out a JHA
JHA requirements.

4. JHA – What is it?
A JHA is a simple risk management tool used to ensure a job or task is performed safely.
It is a more detailed analysis of hazards and risk than a Take-5 or work place inspection.
It is written by the people performing the task (team risk assessment).
Is it reviewed by supervisor(s) prior to the commencement of work.
A JHA uses the same principles as Take 5, but applies those principles in greater detail

5. JHA – Terminology
Hazard Anything which has the potential to cause harm. Control Anything that helps to reduce or eliminate the risk presented by the hazard. Risk Combined measure of the consequence (severity of harm) and the likelihood presented by the hazard.

6. Levels of Risk Assessment
Take 5 or Workplace Inspection
Level 1
JHA
Level 2
Formal Risk Assessment
Level 3

7. Benefits of JHA’s Improves job planning
Identifies hazards associated with task
Identifies controls for managing hazards - thereby eliminating or minimising risk of harm
Provides a review process to ensure line management are aware of moderate and high risk tasks being performed
Assists employees to understand risk management
Demonstrates a structured process for managing risk
Keeps people safe

8. JHA - When must one be done?
When a Take 5 or workplace inspection identifies hazards that are complex, high risk or can’t be readily controlled
When there is no written procedure or safe work procedure for the task
When work permits are required (eg, confined space)
Where there are deviations from standard work practices
If new hazards are identified or the task changes
When existing risk controls are unclear
As the first step in developing a safe work procedure

9. JHA Roles & Responsibilities
Supervisors
Confirm tasks that require JHAs
Discuss JHA requirements at pre-start meetings
Assign a competent JHA team leader to lead the development of JHAs
Review the JHA prior to tasks commencing
Involve managers where necessary to review JHA’s

10. Responsibilities cont.
Team members
Identify tasks that require JHAs
Participate in the development of JHAs
Follow JHAs
Stop work if the task requires steps not covered in the JHA

11. JHA Process
Step 1 : Complete task details Step 2 : Decide job steps Step 3 : Identify hazards Step 4 : Identify existing controls Step 5 : Identify risk rating Step 6 : Identify and implement additional controls Step 7 : Approval and review

12. Number of steps for each job or task
How are the number of steps required for each task determined? We will use the example of changing a flat tyre showing too many steps, too few steps and about the right number of steps………

13. Changing a Tyre – Too Many Steps
Pull off road
Open boot
Put car in ‘park’
Remove jack
Apply hand brake
Remove spare tyre
Activate emergency hazard lights
Etc………………..
Open door
Get out of car
Walk to boot
Put key in lock

14. Changing a Tyre – Too Few Steps
Park car
Take off flat tyre
Put on spare tyre
Drive away

15. Changing a Tyre – Just Right
Park car, apply brake
Remove jack and tyre from boot
Loosen wheel nuts
Jack up car
Remove tyre
Fit new tyre
Jack down car
Tighten wheel nuts
Store tyre and jack

16. JHA Key Points! 3 Key points! Break task into STEPS Identify HAZARDS
Implement CONTROLS to reduce or eliminate the RISK

17. JHA – Requirements
The JHA must be read, understood and signed by all persons doing the job before starting work.
Supervisor must review and sign the JHA before work commences.
All personnel, and both supervisors, must sign on to the JHA for a job that takes longer than one shift.
Area manager must review the JHA where the risk rating is assessed as high or above
If the job changes, or the nature of the hazards change, then the JHA should also be changed
Completed JHAs should be retained by each department for future reference.
Higher level of risk assessment required if uncertain of extent of risk or adequacy of controls.

18. JHA – Requirements
The JHA must be developed by two or more people involved with the task.
All personnel working on the task must have access to the JHA.
A JHA can remain valid for a maximum of 30 days from the approval date (providing that the conditions do not change).
The same JHA can not be used more than once.
Ideally if a JHA is going to be used more than four times a year for the same task then a safe work procedure should be developed.
The work site should be visited to help identify any potential hazards and ensure that the task is understood by those developing the JHA.
The hierarchy of controls should be used with the aim of using the strongest and most effective controls.

19. JHA – Important Points
JHAs do not require as much detail as a safe work procedure (eg, photos / diagrams).
They are a tool for:
breaking a task into steps to understand the hazards and implement effective controls
the development or review of a safe work procedure
implementing effective controls for hazards introduced when work practices / conditions change.
Workgroup involvement provides ownership!
Your JHA can keep YOU safe at work.
